To Become Ghosts (2013)

To Become Ghosts tells the story of 4 friends in their 20s who, seemingly fine on the surface, decide to commit suicide as part of a group pact. Chase somehow survives and is compelled to answer for what he and his friends did. The film is told through an intertwining set of events - a series of flashbacks recounting the evening of the suicide, and the present-day interview between Chase and the journalist.
